"Although Bill Gates stepped away from his day-to-day role at Microsoft nearly five years ago, he still keeps a close eye on the company he co-founded - and he isn't always happy with what he sees. During a recent interview broadcast this morning on CBS This Morning, the Microsoft chairman was asked by Charlie Rose whether he was happy with Steve Ballmer's performance as chief executive. Noting that there have been 'many amazing things' accomplished under Ballmer's leadership in the past couple of years, Gates said he was not satisfied with the company's innovations." It's impossible to deny by this point that Microsoft hasn't done well in mobile. It would be more surprising if Gates had denied it.
